Default Utec for the Nissan 350z....

I appologize in advanced if I missed this but it looks interesting:


http://www.hopupracing.com/tuxsenmasyni.html

Quote:
Fuel Control- The UTEC takes control of your vehicles fuelling at a define-able TPS point that is programmable. Fuel is tuned by an MAF offset table, a simple but effective technique. The load reference we use is RPM vs. MAF Voltage. The UTEC can also take in our optional MAP sensor to tune RPM vs. MAP or you can just use the MAP reading in your datalogs. This allows the fuel map to be adjusted at each of the 250 rpm resolution with over 10 different load sites from zero to rev limit. Ignition Timing- The UTEC gives you complete control of timing. This is not done on the basis of offsets or altering the crank signal as some engine management systems use. The load reference we use is RPM vs. MAF or MAP which is optional. This allows the fuel map to be adjusted at each of the 250 rpm resolution with over 10 different load sites from zero to rev limit. When you enter a value into the Ignition Map you are actually typing in Degrees Before Top Dead Center. The UTEC fires the coils based on these values. No more wondering if the stock ecu is going to advance or retard timing.

Knock Control- This feature allows you to help keep your motor in one piece. The UTEC contains default knock thresholds but can be adjusted at 1000 rpm increments up to 9000 rpm. It also contains a Knock Count threshold that allows you to define how many counts of knock before the UTEC will respond with a Knock Retard Step. The Knock Retard Step is the amount of ignition timing that will be pulled per knock count to a defined Knock Maximum Retard. Knock Maximum Retard relates to the maximum degrees of timing the UTEC will retard per knock event. When a knock count is registered the UTEC will hold the retard for a set number of crank cycles this is called Knock Retard Duration. The UTEC also has the ability to apply a global Knock Correction to the entire map once a knock event is evident. This will help ensure that you keep your high compression monster together. All of these features are the UTEC’s safety net. They should be used pro-active not as a reactive measure.

Datalogging- The UTEC Datalogging function helps you to keep an eye on your engines vitals. Using the logger gives you all the information you want to know about your vehicle. You can take multiple logs of your vehicle whether it’s simple driveability or all out racing. You can be sure the UTEC is keeping an eye out when you can’t. The main logger (Number1) contains rpm, map, maf voltage, tps, load site, afr, ignition timing, injector duty cycle, modified fuel (fuel control) and more. Logs can be output into text files or csv files for easy comparison. When the UTEC is used with a TXS Tuner model it can also supply you with w/b afr readings in your logs as well. Giving you the ultimate tuning package.

Remote Map Selector- The remote selector gives you the capability to switch between your UTEC maps. It also allows you to revert back to full stock ecu control on map 0 (when stock sized injectors are used). Maps 1 through 5 are your UTEC tunable map locations. Map 7 is your security mode, the car will not start. The car cannot be bump started or jumped when security mode is enabled

Software Upgrade- The UTEC will have periodic software updates to further innovate it’s tunability and flexibility. The most current version of software will be available at www.turboxs.com.

The Z UTEC will be ideal for both Forced Induction and Naturally Aspirated Mods. The UTEC has the ability to control things like Nitrous, Water Injection and More!

Not a huge surprise here, but the information in that quote is largely wrong especially in regards to fuel control. The zUTEC has the option of running as a speed density system, a hybrid MAF/SD system, or as a simple offset piggyback for fuel control. The 350z UTEC has just finished up final testing and software work. We have them on the shelf and expect to start shipping them ASAP. It’s likely that we’ll hand deliver the first few units though since the zUTEC is a much different beast then the WRX/STI UTEC. So far we’ve had great success using them on everything from a completely stock G35 to a built motor twin turbo 350z.

The good news for the WRX crowd is that the software for the WRX/STI/EVO UTECs is going to be brought up to date in the near future.

right on. i'm very excited! Do you think you guys might release another base map for the STI? I would love to have something to work off of for my sz55. a 20g/green/superzilla basemap with either perrin or pe injectors would rock.

/me takes a deep breath.


We (utec users) care because any cool freature / research that turboxs put's into other utec platforms trickles down to us. But I think YOU should get a Cobb Accessport.!

So does this mean we will finally get the choice to remove the MAF?

Any chance it will work on the Quest minivan? Supposedly the same engine as the NA 350Z.

Yes, yes I said minivan.

interesting.

i feel myself slowly but surely getting drawn into the utility and ULTIMATE sleeper nature of the minivan.

obviously it has to be highly tunable if i'm ever really going to be satisfied!

I had heard but couldnt find it, that there was a twin turbo Quest running around.
They are actually quite quick. 240hp, 242 ft/lb. It does destroy tires with the traction control off.

Our current plan (which can be revised at any time) is to finally allow this for the WRX/STI/EVO guys. You'll of course need to install an intake air temperature sensor and an appropriate map sensor, but if you've pushed your car to the point where you require a speed density system, you are well beyond "plug and play" and can figure out a little wiring.

Air temperature corrections are easy, so that’s not a big hurdle in tuning a speed density system, but you’ll have a lot of work to do on coolant temperature corrections and cold start should you decide to completely remove your MAF.

In the case of the current release 350z software you do not have the choice of completely removing the MAF just yet because we are not simulating a signal to the stock ECU. We are just completely ignoring the MAF signal and using our own speed-density fuel map where the end user is tuning IPW. This will change in the future, but it is unlikely that it will be until after the WRX/STI/EVO software gets updated.

I am sure that we will be accused of all sorts of evil things here though since every time we release a new software update, a new product, or some upgrade to an existing product these boards fill up with such accusations. I’ll start the first one for you. The SD software is just an evil ploy to get you to purchase TurboXS MAP and IAT sensors. Discuss amongst yourselves…

Will this be compatiable with common sensors? ie. GM 3bar MAP and GM IAT
Since the Utec has the ability to change the MAP calibration any MAP should work. What about IAT will the ability to change the cal on that come with the new software?

Thanks for the new features inadvance it is about time, now you won't get the angry "It is on the website as a feature" calls and posts.

Bastard!

I just want my 5.0 equivalent STI upgrade (1.2? 2.0?). Where do I send my bribes?
I'm not really interested in running SD.

whom will the SD system benefit?

the pump gas sti guys with FP greens, or just the big boys with rotated mount turbos, C16 fiends, etc?

I'm still barely touching 4.9 V MAF. Will the SD system benefit me?

if you're getting 4.9mafv you're well out of the range of its accuracy. i'd be thinking of a bigmaf if you don't switch to SD.

as far as who it would benefit, i'd like to fool around with it so i can just try out a filtered velocity stack right into the compressor inlet.

oh yeah, and run a VTA BOV to rice it up!

hmm I might be a good candidate for beta testing this.

I'm in NoVa, im running a sz55, perrin injectors, and a typhoon intake (so no bigMAF)

I did some trolling of 350z boards this morning and found this link:

http://turboxs.com/utec350zupdate.htm

I grabbed this zip and read the manual:
http://turboxs.com/downloads/350zutec/350Zutec_v2_3.zip


The zutec has a serial port and a USB port. (cool)

I also noticed it has a MAP sensor input.


p.s. Nice job on the manual.

Can you give us any idea of when we might see this update??? I think most of us have been waiting 2 years for this. How about atleast a software update for the STi????

bump... it would be cool at least to have the same features the WRX has. I could really use the WI map.
